This course helps you build essential engineering judgement about water hammer phenomena. Through detailed discussions of case studies the theory, parameters of influence and possible effects are explained. Water hammer assessments are performed for various types of systems in which the influence of system parameters (fluid properties, pipe dimensions & e-modulus, system lengths & heights, steady state pressure, dead-ends & reflections, valve closure times & curves, pump curves, etc) and their effects on pressure transient results are explored.
Included case studies are:
Case study 1: Valve Closure in a cooling water system
Case study 2: Pump trip & cavitation
Case study 3: Filling of an empty fire-fighting system
Case study 4: LNG offloading arms
Case study 5: Complex networks
The course allows you to learn at your own pace and is fully provided online. You receive 1-year unlimited access to all modules, which allows you to perform them over again when you need to refresh knowledge for your work projects.

After opening the course you will be guided step-by-step through the different modules. You receive 1-year unlimited access to the course. This allows you to perform modules again if this is beneficial for your work projects.
Learn by doing.
The course is mainly based on video content: video lectures and video software demonstrations. English subtitles is available and videos can be viewed as many times as desired. The video lectures help you to grasp the important technical concepts and in the video demonstrations the instructor uses the software and discusses all the steps and actions. You are recommended to follow the steps of the instructor in the software to optimize your learning curve.
Exercises & Software models associated with the content are available for download.
This course is self-paced and is not subject to specific dates. The course contains 6 modules with a total of 7 hours of content which can be performed at your own pace. A Personal Certificate will be provided to you if you finish the course within the first month after purchase. This incentive will motivate you to perform the course quickly thereby improving your learning curve.
You receive 1-year unlimited access to all modules. This allows you to perform modules again when you need to refresh knowledge for your work projects.
Participants of this course receive a personal digital certificate if they meet the following requirements:
